Dash rattle?

I have the vehicle listed above with Procomp MT2 tires and Corsa exhaust. I recently took apart my dash to find a source for passenger side rattling. It’s not tweeters, clips, metal-to-metal, broken plastic, loose bolts, nor is it from wiring harnesses. I physically wrapped every male-side clip with cloth tape in an attempt to dampen the rattle; but it’s still happening. Dealership denies hearing it. It rattles when idling and between 20-35 mph.

I’m convinced the rattle is behind the glove box (deeper into dash) because if the rattle was under the hood, I wouldn’t be able to hear it so clearly due to the hum of my tires and exhaust. What do I do now? I don’t want to dismantle the dash again if there is another possible cause to the rattle.
